I sold a lot of top of the tire mount generators in the late 80s for road bikes that mounted where the kickstand is normally mounted---They picked up a lot of road grit. This looks interesting but all the weight is high on the bike.

I'm interested. I have a high-power mid-drive bike, but this would be a simple lower-power addition to a couple bikes I have that don't get ridden enough. It's only good for a dry-weather bike without a rack or fenders, but there's a whole lotta those out there.

I agree--and it is heavy duty road tires only---I would not put it on a 700 x28 narrow road bike tire. The rollers seem to wear out tires quickly---Many years ago we had a gas powered rear motor that applied power through the tire. It ate tires.

I don't understand the fascination with coupling one's phone to a vehicle. Phones run out of battery. Can't read them in bright sun. Their bluetooth and Wifi are problematic. And you expose a $400-1000 phone to weather. Give me a $10 LED display on a cable.

Ditto with the wireless cadence sessor. Who needs to be replacing batteries like I do with the sensor in my $10 bike computers.

Well, it does look attractive to the tool-less contingent. I might throw $89 at one on the used market. Naah. It's too clunky looking.

Today's email said the early bird kickstarter price will be a very low $350! That's probably for just one battery (I don't know -they didn't say in the email but I'm guessing). Still - MUCH more reasonable than their first iteration. I can see where this would be a good alternative for many people. Wouldn't work for me (I use a burley travoy on the back) or for anyone who uses a rear rack for cargo but for straight up commuting with a backpack or front basket, it could work.

I was looking for something I could take with me on trips and attach to a rental bike at the destination site. Key criteria would be portability and ease of install/deinstall on rental bike. As each battery module is 93Wh, I think this would be OK with the airlines. Any opinion on this for that application?

Thanks for the heads up, Linberl, I signed up for emails last night. If they can solve the issue with being able to ride with the motor lifted off the tire, this would work on a light Pashley road bike I own. I'd like to be able to start down my hill non-assist with no drag, then drop the motor down for the climb back home. Should be interesting!

The original version had a mechanism that let you lift up the unit on the seat post and click in place without touching the wheel. I've asked them if this one retains that capacity.

That's how I intend to use my Shareroller, but it definitely allows one to retract the drive head or even remove it and stick in your jacket pocket (retracts into the housing so no grease or dirt). Hopefully, they kept that ability in the new Rubbee version - I'll post back when I hear.

And the answer, for $350 Alex, is..." You can lock ip up in the "lifted up" position so it does not even touch the tire "
That was the answer from Rubbee. Hope that helps. Their first kickstarter for the original Rubbee has some interesting history.
